Safety instructions and measures
Intrinsic safety rendered ineffective in intrinsically safe devices.
Every time the positioner is operated, even not within the plant (e.g. during maintenance,
calibration and work on equipment), it must be ensured that the conditions for intrinsical-
ly safe circuits are observed.
Î Only connect intrinsically safe devices intended for use in intrinsically safe circuits to
certiedintrinsicallysafeinput-connectedunits.
Î Do not place intrinsically safe devices back into operation that were connected to in-
trinsicallysafeinput-connectedunitswithoutcertication.

1.3 Notes on possible property damage
NOTICE
!
Risk of damage to the positioner due to incorrect mounting position.
Î Do not mount the positioner with the back of the device facing upward.
Î Do not seal or restrict the vent opening when the device is installed on site.
Incorrect installation of the lever in positioner versions without a sliding clutch will
damage the travel sensor.
Î Hold the lever in position while removing or mounting it to prevent it from moving to
the end stops.
An incorrect electric signal will damage the positioner.
For the positioner to function properly, a current source and compliance with the pre-
scribed terminal assignment are necessary.
Î Only use a current source and never a voltage source.
Î Connect the electrical wiring to the positioner according to the prescribed terminal
assignment.
